What is a Lottery?


A lottery is a form of gambling in which tickets are sold and the winners are selected by lot. The prizes can be money, goods, or services. In the United States, state governments organize and sponsor lotteries to raise revenue for public purposes. In some cases, a lottery may be used to distribute property or other assets that have been inherited.

During the American Revolution, Benjamin Franklin held a lottery to fund the purchase of cannons for Philadelphia. His attempt failed, but private lotteries flourished, and helped to finance Harvard, Dartmouth, Yale, King’s College (now Columbia), William and Mary, Union, and Brown.

Lottery revenues typically expand dramatically after they are introduced, but then level off or even begin to decline. To maintain or increase revenues, state lotteries constantly introduce new games. This practice obscures the regressivity of the lottery and hides its negative effects on poor people and problem gamblers.

The lottery is an example of the law of diminishing marginal utility, which holds that each additional unit of a good reduces its total utility. Unless the entertainment value (or other non-monetary benefit) of the ticket exceeds the expected utility of winning, the purchase is irrational.

While the chance of winning a lottery is low, many Americans are willing to spend millions of dollars on lottery tickets each year. This behavior can have significant consequences for those who win. If you are considering playing the lottery, it is important to make careful calculations and consider your budget.
